1 Claim.

This invention relates to grilles designed primarily for use in connection with window frames and doors where they are usually employed for protection against intruders.

Grilles of many designs have been devised but in such cases it has been impossible, as far as I am aware, to so construct the grilles that they can be made adjustable to openings of different widths and thusy adaptable to different sizes of doors and window frames.

An object of the present invention is to provide a grille which can be ornamental and which can be adjusted readily to different widths so that one size, if carried in stock, can be used within openings of diierent sizes.

A further object is to provide a grille which is durable and can be made very attractive, the adjustment of the grille making little if any change in the appearance thereof.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changesmay be made in the construction and arrange- .ment of parts without departing from the spirit of the invention as claimed.

the opening in which the grille is to be secured, they being attached to said sides by suitable fastening means as ordinarily.

A top strip 5 is mounted on the upper end portions of the strips I and has its ends curved 5 upwardly as at 6. 'Ihis strip 5 is joined to the curved upper end portions of the strips I by sleeves 'I in the form of narrow bands which are extended around the meeting parts and are in sliding engagement therewith. 10

'I'he grille which has been described is made of a maximum width and when so constructed can be placed bodily in a door or window frame F and the curved ends of the strips I and 5 can then be attached to the frame as stated. If, L5 however, it should be desired to place this grille in a narrower frame such as shown for example at f in Figure 3, the strips I- are swung relative to each other and they act as lazy-tongs so that the overall width of the grille will thus be re- 20 duced until it is the same as the width of the opening in which the grille is to be placed. During this adjustment of the grille the sleeves or slides 'I will move along the top strip 5 leaving the end portions of the top strip projecting be- 25 yond the line of the end portions of strips I. In order to bring this top strip within the confines of the frame f the ends of the top strip strips II are provided, the free end of each of these strips being bent upwardly as shown, at I2 so as to provide a curl or curve such as indicated for example, at 6 in Figure 1. The two strips II`\\ are held together for relative sliding movement by sleeves or bands I3 and these -serve also to couple the upper ends of two of the cross strips I4 to the top member made up of th lapping strips II. They can also be used for holding to this top member a supplemental strip I5 having upwardly curved terminals I6 which serve to add to the attractiveness of the grille by providing these intermediate upstanding portions. 'I'he remaining cross strips extending upwardly to the top member are joined to the said strips by bands I'I so as to be capable of sliding movement relative to the top strips without becoming detached therefrom. Obviously this form of the grille can be readily adjusted in width without changing the configuration of the end curls or upturned portions I2 because should it be desired to make the grille wider or narrower, strips II are merely slid relative to each other and the crossed strips I4 of the grille are swung relative to each other to obtain an adjustment like that acquired with a lazy-tongs.

It is to be understood that other designs of grilles can be made within the scope of the claim forming a part of the present application, all of them utilizing the adjustable feature whereby a grille can be adapted for use in openings of dinerent widths without requiring the services o! a skilled mechanic.

What is claimed is:

In a grille having diagonally intercrossing and relatively riveted bars terminating in scrolls at the perimeter of said grille for xation to the sides and bottom of an opening, means for holding the scrolls along the top of said grille against independent movement relative to the body of said grille, said means comprising a horizontally disposed bar of a length greater than the eiectlve width of said grille and having its ends turned upward and secured to the sides of said opening and means in tight sliding engagement with each of said top scrolls and said horizontal bar intermediate its length to hold said bar and scrolls in rigid relationship with the body of said grille.
